Dealing with Khan would certainly be a challenge, but we had an equal challenge in finding our crew of the Enterprise. While I don't want to approach the second film as a remake of episodes we've seen in the past, and, you know, I don't think any of the other writers and producers are interested in just rehashing, or throwing characters in for the sake of it, and Khan is certainly the most obvious one in the history of the series for me.... Nothing is off limits in terms of what we're discussing.
